![]() ![]() Los aspectos relacionados a la experiencia de participar en proyecto de investigacion cientifica son el fenomeno o caso bajo estudio. Esta investigacion cualitativa propuso como diseno el estudio de caso. Tambien se analizaron: a) las perspectivas del metodo cientifico, b) la estrategia de ensenanza, c) la cultura cientifica y d) la exposicion del proyecto investigativo en la Feria Cientifica como parte del aprendizaje significativo de la ciencias de los participantes. La intencion de este estudio fue indagar en el tema de investigacion cientifica desde el punto de vista de los participantes en los siguientes aspectos relacionados con la experiencia de investigacion cientifica: a) conceptos, b) proceso, c) destrezas y d) disposicion. La ciencia es el eje fundamental a traves del cual se desarrollan las habilidades necesarias para el pensar cientifico que va a la busqueda del conocimiento cientifico. It is published semiannually, and includes reports of both quantitative and…Įl aprendizaje significativo en las ciencias al participar en proyectos de investigacion cientifica This review of educational investigation seeks to promote the exchange of information about empirical research in education. This document consists of the eight issues of the series "Revista Investigacion Educativa" published during the 4-year period 1992-1995. Revista Investigacion Educativa, 1992-1995.ĮRIC Educational Resources Information Center The influence of temperature, fluidization velocity, oxygen excess, Ca/S ratio and coal properties have been studied in relation to the combustion efficiency, sulfur retention, CO and NO emissions.« less The combustion trials have been done in a circulating fluidized bed pilot plant with a 200 mm inside diameter and a height of 6.5 m. In order to reduce the sulfur in the flue gases, a high calcium content limestone has been used as sorbent. The bituminous coal and the anthracite have 1% and 2% sulfur content respectively and the sulfur is pyritic in these cases. The two lignites have very high sulfur content (7% and 8%) but the sulfur is organic in one case and pyritic in the other. Two lignites, a bituminous coal and an anthracite. ![]() This paper reviews the major results of the fuel program in order to determine the fluidized bedmore » combustion performance of four fuels. The Centro de Investigaciones Energeticas, Medioambientales y Tecnologicas is carrying out a program with the intention of assisting companies in evaluating fuel quality impact, using atmospheric fluidized bed combustion. The Circulating Fluidized Bed Combustion process enables an efficient use of this coal. The use of this coal, by conventional combustion processes in power and industrial plants, implies a very high environmental impact. The major part of the Spanish coal supply is low range coal with both high ash (20-40%) and sulfur (1-8%) content. This paper describes the development of the methodology and illustrates its use.« lessĬharacterization of coals for circulating fluidized bed combustion by pilot scale tests It can be used to assess engineered barrier performance, the attenuating properties of host geological formations, and the long term impacts of a facility on the environmentmore » and human health, as well as allowing the comparison of different disposal options for radioactive, mixed and non-radioactive wastes. ![]() This Safety Assessment Comparison (SACO) Methodology employs a systematic approach to the collection, evaluation and use of waste and disposal system data. Development and application of a safety assessment methodology for waste disposalsĭOE Office of Scientific and Technical Information (OSTI.GOV)Īs part of a European Commission funded research programme, QuantiSci (formerly the Environmental Division of Intera Information Technologies) and Instituto de Medio Ambiente of the Centro de Investigaciones Energeticas Medioambientales y Tecnologicas (IMA/CIEMAT) have developed and applied a comprehensive, yet practicable, assessment methodology for post-disposal safety assessment of land-based disposal facilities.
